Ex-Alta 1: University of Alberta's first CubeSat

Thanks to funding from the Canadian Space Agency, students from the University of Alberta have built a CubeSat that was deployed into space from the International Space Station on May 26, 2017, as part of the international QB50 mission.

The CubeSat, named Ex-Alta 1, will collect information on space weather with the help of a miniaturized version of a science instrument called a magnetometer, an essential tool for studying solar storms.

What is the QB50 Mission?

QB50 is an international space mission funded by the European Commission. It provides a unique, hands-on experience to university students around the world. Each team is responsible for designing, building and operating a CubeSat, allowing the team members to acquire new skills in space science and technology, as well as abilities like how to communicate science.

A dedicated team

The Ex-Alta 1 CubeSat is made up of three units and is about the size of a loaf of bread. It is the result of seven years of work by AlbertaSat, a team of undergraduate and graduate students under the supervision of professors from the University of Alberta.
